We will focus on corollary benefits with the use of HemaClear®, a self-contained, sterile, exsanguinating auto-transfusion tourniquet. This discussion will demonstrate that the use of auto-transfusion tourniquets is a practical evidence-based approach in fluid resuscitation: it shortens the duration of shock after hemorrhage and trauma compared with conventional tourniquets. Emphasis is placed on the use of the HemaClear® as an alternative fluid resuscitation tool which is more efficient in the battlefield, pre-hospital and in-hospital settings.Keywords: auto-transfusion tourniquet, field exsanguination, hemorrhagic shock, tourniquet, perfusion requirement, HemaClear® AT
